How do I charge monthly for a weekly service? -

Ok now im probably retarded or something but I am starting a service business and am trying to figure out how I can charge my customers one time a month for a service I charge weekly... For example if i want to charge say $50 a week but i want to only bill them one time a month, But the same price every month, say $200 .. How do i manage this without out falling behind or be ahead with my service? Does this make sense?

I think you should go with $215 or $220.My reasoning: The only month with nearly exactly 4 weeks in it is February. All the other months are 4 weeks and two or three days.Days in year = 365. Average days per month = (365/12) = 30.4Average weeks per month = (30.4 / 7) = 4.34If you want to charge $50 per week, the monthly amount would be (4.34 x $50) = $ 217----------------So yeah, I d go with a monthly charge of $220 (or $54 per week), otherwise you re gyping yourself out of getting paid for those extra days in the longer months.
